Actress and campaigner Alyssa Milano has weighed in on a viral video that appeared to show Make America Great Again-hatted high school boys chanting in the face of a Native American veteran near the Lincoln Memorial in Washington, D.C.

“The red MAGA hat is the new white hood," Milano tweeted Sunday, appearing to compare the Trump campaign merchandise to robes worn by the Ku Klux Klan. "Without white boys being able to empathize with other people, humanity will continue to destroy itself.”

The tweet was one ofseveral posted by the actress apparently in reference to hotly debated viral footage of the group of boys from Covington Catholic High School in Kentucky. The students were in the capital for an anti-abortion "March for Life" rally, while the Native American campaigner pictured in the video›—Nathan Phillips—was taking part in the Indigenous Peoples' March.

Phillips told the Detroit Free Press he had intervened in a standoff between the boys and a few members of a group called the Black Hebrew Israelites. He said he put himself between the two groups to defuse the situation. The students, he added “were in the process of attacking these four black individuals.”

But some have argued the boys' behavior was provoked. “All they’re doing is waiting to get on a bus and they’re being yelled at by grown men. Why are they the bad guys?” parent Jim Wilson told CBS Evening News with Jeff Glor.

The original footage provoked such controversy it was eventually removed by Twitter Monday for breaking the social media site’s rules. As a company spokesperson told The Hill, “Deliberate attempts to manipulate the public conversation on Twitter by using misleading account information is a violation of the Twitter Rules.”

Responding to the controversy surrounding the footage, Milano tweeted Monday: “Let’s not forget—this entire event happened because a group of boys went on a school-sanctioned trip to protest against a woman’s right to her own body and reproductive healthcare. It is not debatable that bigotry was at play from the start.”

Hoda Muthana's father, Ahmed Ali Muthana, filed the lawsuit in Washington D.C., and "seeks injunctive relief preventing the United States government from unconstitutionally robbing (Muthana and her son) of their rights as United States citizens."

"The ice doesn’t care what this administration thinks. It’s just going to keep melting," David Titley, the director of the Center for Solutions to Weather and Climate Risk at Penn State, told Newsweek.
